Research ArticleOpen accessIn the abstractStressors Influence on Salmonella enterica Serovar Enteritidis Colonization in BroilersE. S. Soliman, E. Taha, K. D. Infante et al.Problem statement: Poultry industry usually exposing birds to a variety of actions and stressors includs fasting for gastrointestinal emptying before transportation and where birds are often exposed to high environmental temperature during the summer months. These environmental stressors may have influences on bird performance and susceptibility to pathogens such as Salmonella enteritidis by altering the intestinal micrbiota and changes in … …American Journal of Animal and Veterinary Sciences, Vol. 4, Issue 3 · 12 Sep 2009 · 7,187 accessesView PDFCite
Research ArticleOpen accessIn the abstractEpidemiology of Human Herpesvirus Type 8 Infection in Cardiopathic PatientsAngela Ingianni, Maria A. Madeddu, Francesca Carta et al.Problem statement: The possible contribution of viruses to vascular pathology is still a controversial issue. Human herpesvirus type 8 (HHV-8) has been suggested to participate to the pathogenetic events associated with atherosclerotic lesion establishment and progression. Recently, a high incidence of infection of HHV-8 (11%) has been verified in the island of Sardinia. The aim of this study was to … …OnLine Journal of Biological Sciences, Vol. 9, Issue 2 · 30 Jun 2009 · 7,334 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnti-Inflammatory Activity of Vitex leucoxylon L. Bark Extracts Against Freund's Complete Adjuvant Induced Arthritis in Sprague Dawley RatAlluri V. Krishnaraju, Chundi B.M. Rao, Dodda Sundararaju et al.Problem statement: Anti-inflammatory agents, particularly steroids and cyclooxygenase inhibitors are often associated with adverse side effects including, GI irritation, ulcers, hypertension and cardiac abnormalities. A safe and effective intervention is essential for the treatment of inflammatory disorders. Approach: Abstract Vitex leucoxylon L., a medicinal plant of the verbenaceae family, used in traditional medicine for relieving headache and catarrh. VL-89/185A, was … …American Journal of Infectious Diseases, Vol. 5, Issue 2 · 30 Jun 2009 · 8,044 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Optimized Medium for Screening of L-Asparaginase production by Escherichia coliYounes Ghasemi, Alireza Ebrahiminezhad, Sara Rasoul-Amini et al.Purified L-asparaginase II from Escherichia coli has been supplied and employed in the acute leukemia and other malignant neoplasms chemotherapy. L-asparaginase II gene (ansB) in E. coli is under regulation and certain conditions is needed for expression of this gene. In this investigation ,the various concentrations of modified M9 medium ingredients and various carbon source were tested to optimize the … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 4 · 31 Dec 2008 · 9,698 accessesView PDFCite
Research ArticleOpen accessIn the abstractCentral Nervous System Tuberculomas: A Review ArticleMutasem Abuhamed, Xiao Bo, Cai YanCentral Nervous System Tuberculomas (CNSTs), the most dangerous form of tubercolomas, remains a public health problem, particularly in the developing country. Central nervous system tuberculomas, either single or multiple, usually presents as a diagnostic challenge because it resembles many other infectious and non-infectious medical conditions, particularly in patients without constitutional symptoms or evidence of tuberculosis elsewhere in the body. Here … …American Journal of Infectious Diseases, Vol. 4, Issue 2 · 30 Jun 2008 · 7,484 accessesView PDFCite
Research ArticleOpen accessIn the abstractHormetic and Non-Hormetic Dose-Response Functions in Stress Effects on Memory and Synaptic Plasticity: Issues and MechanismsPhillip R. Zoladz, David M. DiamondOver a century of behavioral research has shown that stress can exert both positive and negative effects on memory. We have explored the idea that the complex effects of stress on learning and memory can be characterized by hormetic- and non-hormetic dose-response functions, in which stress may either stimulate or impair brain memory mechanisms, depending, in part, on the timing … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 1 · 31 Mar 2008 · 8,184 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Mathematical Modeling Approach to Characterize Hormesis, Caloric Restriction and Toxicity in Mortality Data from Toxicity StudiesPatricia J. NeafseyThe mortality of a population reflects the combined effects of natural aging with environmental insults (e.g. toxicant exposure, caloric restriction, over feeding, infections, etc.). No single endpoint, such as carcinogenesis, completely describes toxicant-induced effects in laboratory animals. Mathematical models of mortality and time-dependent exposure to toxicants can yield indices of net injury from all causes. With careful manipulation of diet … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 1 · 31 Mar 2008 · 7,160 accessesView PDFCite
Research ArticleOpen accessIn the abstractHormesis and Exercise: How the Cell Copes with Oxidative StressLi Li Ji, Zsolt Radak, Sataro GotoContraction-induced production of reactive oxygen and nitrogen species has been shown to cause oxidative stress to skeletal muscle, heart and other organs. As an adaptive response, muscle antioxidant defense systems are upregulated in response to exercise to restore intracellular prooxidantantioxidant homeostasis. Thus, both young and old animals and humans involved in regular exercise have shown reduced oxidative damage during acute … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 1 · 31 Mar 2008 · 7,817 accessesView PDFCite
Research ArticleOpen accessIn the abstractImportance of blood gas measurements in perinatal asphyxia and alternatives to restore the acid base balance status to improve the newborn performanceH. Orozco-Gregorio, D. Mota-Rojas, M. Alonso-Spilsbury et al.Prolonged or intermittent asphyxia in utero and during farrowing weakens piglets and renders them less capable of adaptation to extrauterine life. Piglets with lesser viability at birth have increased blood pCO2 and blood lactic acid concentrations and decreased blood pH. Moreover, the ability to thermoregulate during an acute cold stress is inversely related to umbilical blood lactate concentrations. Blood gas … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 3 · 30 Sep 2007 · 7,631 accessesView PDFCite
